The Allen-Bradley 1769-IF4I is a part of the 1769 CompactLogix 5370 Controller series. It is an Analog Current/Voltage Isolated Input Module with 4 differential analog input channels. It digitally stores and converts analog data for use by controllers like the MicroLogix 1500 controller and the CompactLogix controller. It has dimensions of 4.65 x 3.43 x 1.38 in. and a weight of 0.65 lbs. The module must not be installed more than 8 modules away from the system power supply. It has a maximum heat dissipation of 3 Watts. For installation, it has Panel or DIN Rail mounting options and an open enclosure.
It thus allows for a common development environment with high performance and low cost. It has removable terminal blocks which provide greater user flexibility for installation and wiring. For communication with the controller, it uses the bus interface. The 1769-IF4I also receives 5 and 24V DC power through its bus interface.
